As the field of topological magnetic textures is strongly inspired and shaped by the observations made in bulk materials, there is great interest to create samples of reduced dimensions, such as thin films or nano-structured specimens, from those materials which display long-wavelength, topological spin textures in their bulk. Yet, growing evidence establishes that the properties of bulk materials prepared in reduced dimensions differ substantially from genuine bulk dimensions. Typical open questions may be illustrated nicely in the class of cubic chiral magnets, where the magnetic phase diagrams differ distinctly between bulk samples and epitaxial films [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}. Further, epitaxial films prepared from cubic chiral magnets present an interesting case where a determination of the ground state magnetic configuration is unresolved [9]}, [4]}, [5]}, [12]}, [13]}. In addition, the surfaces of cubic chiral magnets appear to support an unexplained strong Néel twisting [14]}. Last but not least, even metastable surface configurations, known as chiral bobbers, may completely change the energetics of samples with reduced dimensions [15]}.
